Scientists Map Brain Circuit That Drives Activity in Fertile Females

Mouse study identifies specific neurons and a signaling pathway to regions of the hindbrain that mediate sexual reproductive activity and physical activity that appear to influence activity behaviors during ovulation. The findings may provide valuable insights into how estrogen loss during menopause disrupts this activity.
